- the present invention relates to a pellicle for lithography and a method of manufacturing the same.
- the exposure technology using an excimer laser is no longer able to cope with the patterning of the further miniaturized line width of 32 nm or less scheduled for the next generation, and light with a shorter wavelength compared with the excimer laser.
- An EUV exposure technology using Extreme Ultra Violet (EUV) light with a dominant wavelength of 13.5 nm is expected.
- the unsolved technical problems of pellicles used for EUV exposure are (1) development of a material having high transparency to EUV light and being chemically stable, (2) in the case of an ultra thin film Keeping the permeable membrane (pellicle membrane) inevitably under tension without loosening, (3) enabling use under vacuum after attaching to a photo mask under normal pressure And so on.

- the temperature at the time of applying the silicon film is room temperature or A degree slightly higher than room temperature is desirable.
- strong stress is already introduced into the silicon film of the conventional method as described above in the deposition process (sputtering process, CVD process, etc.).
- these silicon films are not single crystal silicon films, the amorphous portions and grain boundaries contained in the films cause the absorptivity (absorption coefficient) of EUV light to be high and the transmittance to decrease. It will Furthermore, the film is chemically unstable and easily oxidized, so that the transmittance for EUV light decreases with time, and the film can not withstand practical use.

- 5A to 5J are views for explaining a second example of the method for manufacturing a pellicle for lithography of the present invention.
- the silicon film for pellicle for EUV exposure that has been reported conventionally is formed by the sputtering method or the CVD method. In this case, the film becomes amorphous or polycrystal, and the absorptivity (absorption coefficient) of light in the EUV wavelength range increases. Therefore, the inventors of the present invention have made the present invention by repeating studies using a single crystal silicon film as a pellet film.
- FIG. 1 is a diagram showing the absorption coefficient of a single crystal silicon film for light of a wavelength near 13.5 nm in comparison with the absorption coefficient of an amorphous silicon film.
- the single crystal silicon film has an absorption coefficient of about 40% as compared to the absorption coefficient of the amorphous silicon film, and has high transparency to light in the EUV wavelength band, It has excellent properties as a pellicle membrane.
- the absorption coefficient shown in FIG. 1 see, for example, Edward D. Palik, ed., “Handbook of Optical Constants of Solids,” Academic Press, Orlando (1985) (Document 3).
- the present inventors use an SOI substrate provided with a single crystal silicon layer as an SOI layer to realize a pellicle for lithography provided with a single crystal silicon film as a pellicle film, and use the single crystal silicon layer as a pellicle film.
- investigations were made on a method of forming the supporting member of the pellicle film by processing the base substrate (handle substrate) of the SOI substrate.
- the pellicle obtained by such a method not only has the advantage of high transparency to light in the EUV wavelength range, but also forms the pellicle film after separately forming the pellicle film and the supporting frame as in the prior art. There is also an advantage of eliminating the need for the effort of stretching on a frame.
- FIGS. 2A and 2B are views showing the structure of the pellicle for lithography of the present invention, wherein FIG. 2A is a bottom view and FIG. 2B is a cross-sectional view along AA shown in FIG. 2A.
- the pellicle for lithography of the present invention is provided with a pellicle film 10 of single crystal silicon, and the pellicle film 10 comprises an outer frame portion 20a and a porous portion 20b in the inner region of the outer frame portion 20a. It is supported by a support member 20 having a (mesh structure).
- anti-oxidation films 30a and 30b are formed which cover the portion where the single crystal silicon film is exposed to the outside.
- the portion indicated by reference numeral 40 in the drawing is the portion which was the insulator layer (BOX layer) of the SOI substrate.
- the ones indicated by reference numerals 50a and 50b in the figure are filters provided in the frame portion 20a of the support member 20, and it is possible to adjust the internal pressure at the time of using the pellicle by allowing the gas to permeate through the filters. It is a thing.
- FIG. 3 is an enlarged optical photomicrograph showing the mesh structure of the pellicle for lithography of the present invention.
- the portion indicated by “M” is the mesh structure portion of the support member
- the portion indicated by “P” is the pellicle film portion of single crystal silicon which is bored from the hole portion of the mesh structure portion.
- a large number of substantially hexagonal hole portions having a diameter of about 200 ⁇ m are formed in the inner region of the outer frame portion of the support member, and the distance between the hole portions is approximately 20 ⁇ m.
- a pellicle film portion of single crystal silicon can be observed from these holes, and light at the time of exposure is irradiated from the portion to a photomask (reticle).
- the handle substrate of the SOI substrate is described as a silicon substrate, but may be another substrate (for example, a glass substrate or a quartz substrate).
- an SOI substrate for producing a pellicle having the above-described configuration for example, an SOI substrate produced by bonding single crystal silicon wafers crystal-grown by a CZ method via an oxide film can be used.
- Such an SOI substrate can be obtained, for example, by the following procedure.
- a uniform ion-implanted layer is formed to a depth (average ion-implantation depth L) and surface activation is further performed by plasma treatment or the like.
- the first single crystal silicon substrate subjected to surface activation and the second single crystal silicon substrate are adhered in close contact with each other, and the above-described ion implantation layer is utilized to form a first single crystal silicon substrate. Mechanically peel off the silicon layer.
- an SOI substrate having a silicon layer (SOI layer) on a second single crystal silicon substrate can be obtained.
- the porous portion (mesh structure) is provided in the inner region of the outer frame portion of the support member included in the pellicle for lithography of the present invention is that the thickness of the single crystal silicon pellicle film of the pellicle for EUV is several tens nm to several hundreds nm This is because it is extremely difficult to support such a thin pellicle membrane in a stable and mechanical strength secured state only by the pellicle frame (outer frame portion).
- a method is employed in which a mesh structure is made of metal and a pellicle film of amorphous silicon is bonded to the mesh structure using an organic substance as an adhesive.
- an organic substance as an adhesive.
- it is difficult to cause the entire surface of the pellicle film to adhere to the mesh structure uniformly and with high accuracy.
- stress adjustment of the pellicle membrane is extremely difficult.
- the method of processing the handle substrate of the SOI substrate as a support member is selected. That is, the handle substrate is ground and polished from the back surface to a desired thickness, and the handle substrate is partially removed to form holes to form a mesh structure.
- dry etching by a silicon DRIE (Silicon Deep Reactive Ion Etching) method widely used in MEMS and the like can be used.
- the etching is stopped at the insulator layer (BOX layer) such as a silicon oxide film (or the etching rate becomes extremely slow), and therefore, it is used as a pellicle film.
- the single crystal silicon layer (SOI layer) is not etched. Further, since the pellicle film of single crystal silicon is firmly bonded to the support member, sufficient mechanical strength can be secured. Furthermore, since no adhesive is used, contamination due to the remaining organic matter is also avoided.
- a film made of an inorganic material such as SiON, SiC, Y 2 O 3 , YN, or at least one of these materials can be obtained by forming a film on the surface of the single crystal silicon layer.
- the formation of the antioxidation film can also be performed by a method such as a CVD method, a sputtering method, or an electron beam evaporation method, but according to the ion beam aided evaporation method or the assisted gas / cluster ion beam (GCIB) evaporation method Since a dense film having a high density close to the theoretical density can be formed, and high oxidation resistance can be obtained even if the antioxidant film is made thin, the high transmittance is not impaired. Regarding this point, for example, L. Dong et al. Journal of Applied physics, vol. 84, No. 9, pp. 5261-5269, 1998 (Document 4), “Kyber ion beam basics and applications” edited by Yamada Kou See Chapter 4 Nikkan Kogyo (Document 5).
- the internal pressure adjustment is required, but the mechanism of such pressure adjustment is required to be capable of preventing the entry of foreign matter at the time of gas inflow and outflow.
- a filter such as ULPA or a metal filter that can capture extremely fine foreign matter is preferable.
- it is important that such a filter has an area such that the pellicle membrane does not expand and contract or break due to the uneven pressure difference.
- FIGS. 4A to 4G are views for explaining a first example of a method of manufacturing a pellicle for lithography of the present invention.
- an SOI substrate is prepared (FIG. 4A).
- an SOI layer 20 of single crystal silicon is provided on a handle substrate 20 via a BOX layer 40 of a silicon oxide film.
- the thickness is about 700 ⁇ m, so the handle substrate side may be thinned by grinding, polishing or the like to a desired thickness (for example, 400 ⁇ m or less). This is because if the height of the support member is higher than necessary, a burden will be imposed on the subsequent etching step. In addition, if the handle substrate side is made thinner in advance, the time required for the etching process can also be shortened.
